Application filed January 11, 1904. Serial No. 188,472. (No modeLl To all whomit may concern/.3

Be it known that I, 'JoHN SALTAR, J r of Philadelphia, in the State of Pennsylvania, have invented-certain new and useful Improvements in Gas-Retort Chargers, whereof the following is a specification, reference being had tothe accompanying drawings.- 1 My improvements relate-t apparatus for feeding fuel to gas-generators, and comprising a rotative or oscillative vessel having an" opening in the top into which a charge of fuel .is' primarily received and which is quickly" semirotated with respect to the retort or pro- 'ducer casing in order to empty the fuel charge into the latter, after-which the' vessel is as quickly reversed, mouth upward, ready to receive another charge. 4 r i I r As hereinafter described, my nvention comprises a rotative or oscillative fuel vessel fitted to a seat in the mouth of sucha casing-or retort, open on one side to recelve thecharge,

provided with means whereby it may be rocked to deliver the charge to theretort, and also provided with means to-press the vessel upon said seat to securely seal the retort during the intervals between successive charging opera-' tions. J

In the form ofmy invention hereinafter described the trunnions upon which the receiving vessel isarranged to be rocked are mounted in bearings provided with means to adjustably increase and diminish the pressure of said vessel upon its seat in the mouth of the retort and also to vary the position of said vessel to accuratelyfitsaid'seat and compen' sate for wear of the parts.

- My invention comprehends the various-novel features of construction and arrangement hereinafter more definitely specified and my-invention. the device, taken'on the-line II II in Fig; I.

Fig. III is a transversese'ctional view of the Visa side view of the upper portion of a gasproducer casing or retort provid'ed with modified means for adjusting the charging vessel. Figs. VI and VII are sectional views showing *modified 'forms'of charging vessel's. Fig.

VIII i's'a side view of'the upper portion of a gas-producer casing or retort, showing'a modified embodiment of my invention Fig. IX is asectiona'l view't'aken on the line IX IX in In said figures, 1 is the gas-producer casing or retort, whose mouth2 is provided with the flange-seat-B. The bearing-housings Land 5 are mounted'in alinement on opposite sid'es of said retort-mouth, as best shown in Fig. II, and serve to support the hopper 6 in registry with the fuel-opening 7 in the charging vessel 8'." The trunnions 9. and, 10 'of said vessel 8' are respectively mounted in slide-bearing boxes 'll'and 12, and, as' shown in Figs. I, II,

f and IV, the-trunniOn'IO is provided with the 'lever-handleld', by which said vessel8 may be rocked in said bearings to deliver the fuel charge through the; retort-mouth.

The bearing 11 is' maintained indefinite but variable position, with respect to the housing 4 by meansv of the adjustingscrew 16, which is in threaded engagement with the aperture 17 in'said housing and prdvided with the jam-nut 18. r I V 1 The bearing 12 is provided with the adjustingscrew 20, which isentered in threaded engagement with the opening 21 in the strap 23 and provided with the jam-nut 24. As shown in Figs. II and IV, thestrap 23 is mounted upon the e'c'centric'portion 26 of the shaft; 27, whose' opposite concentric ends .are mountedin the bearing-lugs 29 30 of the housing 5. Said shaft is provided with the operating-le- Y ver 31, by which'it may be oscillated to raise In the drawings, FigureI is' 'a side view of the upper-portion of a gas-producer casing or retort, showing a convenient embodiment of Fig. II. is a'sectional view of upon the point of the adjusting-screwlb Other means than those above described may be employed to vary the pressure of the charging vessel'upon its seat in the mouth of the retort. For instance, in Fig. V the trunnion'35 of the charging vessel 36 is mounted in the slide-bearing 38, which may be pressed down or released by the adjusting-screw 39, which is in threaded engagement with the housing 40 and provided with the handle 41- that is to say, the adjusting-screw 39 and its handle 41 can effect the same variation in pressure on the vessel as the adjusting-screw 20, strap 23, eccentric 26, and lever 31, above described.

As indicated in Figs. II and III, the interior of the charging Vessel may be provided with the diaphragm or rib 9. Said diaphragm or rib stiffens the vessel between its supportingtrunnions and thus prevents distortion of the vessel-walls and consequent leakage between said walls and the seat when the clamping pressure is applied to'the trunnions and insures that the fuel shall rotate with the vessel, thus aiding in preventing it spilling, and also facilitates the discharge of the fuel when the vessel isin proper position therefor.

In Figs. I to V, inclusive, the charging vessel is spherical in form, and therefore adapted to fit a circular seat in the retort. However, it is to be understood that any form of vessel may be employed which has a surface of revolution of such extent that a seat can be made which will fit the vessel closely both in the position for receiving the fuel charge and in the position for emptying the same into the retort. For instance, Fig. VI shows the vessel 43 so shaped as to fit the seat-flange 44, surrounding the mouth 45, which is of irregular contour. Fig. VII shows the vessel 46 of such configuration as to fit the seat-flange 48 around the mouth 49, which is of double hyperbolic contour, and Figs. VIII and IX show a cylindrical vessel with a cylindric seat.

Referring to the form of my invention shown in Figs. VIII and IX, the producer casing or retort 50 is provided with a flange-seat 52 at its mouth 53, and the bearing-housings 54 and 55, alined on opposite sides thereof, support the hopper 56 in registry with the fuel-opening 57 in the cylindrical charging vessel 58. The trunnions 59 and 60 of said vessel 58 are respectively mounted in slide-bearing boxes 61 and 62, provided with springs 65 and 66, which tend to press the vessel 58 upon its seat and seal said retort 50. The trunnion 60 is conveniently provided with the lever-handle 68, by which the vessel 58 may be rocked upon said seat 52.

It may be noted that the various forms of fuel-charging vessels above described are similar in that their perimeters are symmetrical with respect to their axes of rotation, so-as to present equal cross-sectional areas within the retort-mouths in different rotary positions of said vessels, and that said vessels are each arranged to hermetically seal its retort in both the position for receiving the fuel charge and in the position for emptying the same into the retort, so as to prevent the passage of air or gasv through the retort-mouth. It must also be noted that my improvements are advantageous over the single or double bell-valve, as well as the large gas-valves and other similar arrangements now in use as gas-retort chargers, because in all of these devices the dirt and dust of the fuel are placed in actual contact with the finished surfaces of the valves and their seats, thus. preventing a clean and gas-tight joint, whereas in my improvements none of the fuel or its dirt comes in contact with the finished surfaces either of vessel or seat and the rocking of the vessel upon its seat tends continually to wear the seat to a tighter fit.

Although I prefer to provide the charging vessel with distinct means to adjustably press it upon its seat at the retort-mouth, as above 7 described, it may be noted that an air-tight joint may be maintained between the retortmouth and the vessel by the mere weight of the latter. Moreover, it is obvious that various modifications may be made'in the details of construction and arrangement of my invention without departing from its essential features.

In a gas-retort charger, the combination with a retort having a mouth surrounded by a seat; of a charging vessel constructed to oscillate to deliver fuel to the. retort; and, means arranged to vary the pressure upon said vessel to alternately seal the retort-mouth and permit the movement of said vessel, substantially as set forth.
